Abstract
A system can comprise a processor and a memory embodying an application. The application can comprise code that causes the processor to identify a client key embedded or hard-coded in the application (i.e., included as part of the code comprising the application). Additional code causes the processor to identify data to be accessed according to an encrypted license accessible through use of a machine key. The application can maintain the machine key in an encrypted state using the client key. The application can include code that causes the processor to determine if an encrypted version of the machine key accessible by the processor can actually be decrypted using the client key. If so, the client key can be used to access the machine key. If not, the processor can request a differently-encrypted version of the machine key from a migration service.
